653 Older Version : 00.00.04.17.1-rc1

671. Add the Online Controller Reset (OCR) to the Driver.
68 OCR is the new feature for megaraid_sas driver which
69 will allow the fw to do the chip reset which will not
70 affact the OS behavious.
71
72 To add the OCR support, driver need to do:
73 a). reset the controller chips -- Xscale and Gen2 which
74 will change the function calls and add the reset function
75 related to this two chips.
76
77 b). during the reset, driver will store the pending cmds
78 which not returned by FW to driver's pending queue. Driver
79 will re-issue those pending cmds again to FW after the OCR
80 finished.
81
82 c). In driver's timeout routine, driver will report to
83 OS as reset. Also driver's queue routine will block the
84 cmds until the OCR finished.
85
86 d). in Driver's ISR routine, if driver get the FW state as
87 state change, FW in Failure status and FW support online controller
88 reset (OCR), driver will start to do the controller reset.
89
90 e). In driver's IOCTL routine, the application cmds will wait for the
91 OCR to finish, then issue the cmds to FW.
92
93 f). Before driver kill adapter, driver will do last chance of
94 OCR to see if driver can bring back the FW.
95
962. Add the support update flag to the driver to tell LSI megaraid_sas
97 application which driver will support the device update. So application
98 will not need to do the device update after application add/del the device
99 from the system.
1003. In driver's timeout routine, driver will do three time reset if fw is in
101 failed state. Driver will kill adapter if can't bring back FW after the
102 this three times reset.
1034. Add the input parameter max_sectors to 1MB support to our GEN2 controller.
104 customer can use the input paramenter max_sectors to add 1MB support to GEN2
105 controller.

267 (max_sectors_1, max_sectors_2). For certain controllers/FW,

328 It does, but the DMA API was expanded to cope with this exact case, so
329 use dma_alloc_coherent() directly in the megaraid code instead. The dev
330 is just &pci_dev->dev.

358i. Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
359
360 Fix: The driver is now throttling IO.
361 Checks added in megasas_queue_command to know if FW is able to
362 process commands within timeout period. If number of retries
363 is 2 or greater,the driver stops sending cmd to FW temporarily. IO is
364 resumed if pending cmd count reduces to 16 or 5 seconds has elapsed
365 from the time cmds were last sent to FW.
366
367ii. FW enables WCE bit in Mode Sense cmd for drives that are configured
368 as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical
369 Disks are exposed with WCE=1. User is advised to enable Write Back
370 mode only when the controller has battery backup. At this time
371 Synhronize cache is not supported by the FW. Driver will short-cycle
André Goddard Rosaaf901ca2009-11-14 13:09:05 -0200372 the cmd and return success without sending down to FW.

4373 Older Version : 00.00.02.04
438
439i. Added support for ZCR controller.
440
441 New device id 0x413 added.
442
443ii. Bug fix : Disable controller interrupt before firing INIT cmd to FW.
444
445 Interrupt is enabled after required initialization is over.
446 This is done to ensure that driver is ready to handle interrupts when
447 it is generated by the controller.

466
467i. Support for 1078 type (ppc IOP) controller, device id : 0x60 added.
468 During initialization, depending on the device id, the template members
469 are initialized with function pointers specific to the ppc or
470 xscale controllers.

478i. Register 16 byte CDB capability with scsi midlayer
479
480 "Ths patch properly registers the 16 byte command length capability of the
481 megaraid_sas controlled hardware with the scsi midlayer. All megaraid_sas
482 hardware supports 16 byte CDB's."

490i. New template defined to represent each family of controllers (identified by processor used).
491 The template will have defintions that will be initialised to appropritae values for a specific family of controllers. The template definition has four function pointers. During driver initialisation the function pointers will be set based on the controller family type. This change is done to support new controllers that has different processors and thus different register set.

499i. Code reorganized to remove code duplication in megasas_build_cmd.
500
501 "There's a lot of duplicate code megasas_build_cmd. Move that out of the different codepathes and merge the reminder of megasas_build_cmd into megasas_queue_command"

503 - Christoph Hellwig <hch@lst.de>
504
505ii. Defined MEGASAS_IOC_FIRMWARE32 for code paths that handles 32 bit applications in 64 bit systems.
506
507 "MEGASAS_IOC_FIRMWARE can't be redefined if CONFIG_COMPAT is set, we need to define a MEGASAS_IOC_FIRMWARE32 define so native binaries continue to work"
